摘要 目的:建立稳定表达缺失型DNA聚合酶β(polβ)的细胞系。方法:将已构建的缺失型polβ的真核表达载体pcDNA3.1-polβ用脂质体法转染中国仓鼠卵巢细胞(CHO),经G418筛选后得到稳定转染的细胞株,用RT-PCR方法鉴定细胞缺失型polβmRNA的表达。结果与结论:成功转染和筛选出表达缺失型polβ的细胞株CHO-polβ,建立了稳定表达缺失型polβ的CHO细胞株。 Aim: To establish a cell line stably expressing mutant (58 bp deletion)DNA polymerase β( DNA polβ). Methods : The constructed eukaryotic expression vector carrying mutant DNA polβ gene was transfected into Chinese hamster ovary cell (CHO) by the lipotransfection. The stable transfectants were screened by G418. The mRNA expression of mutant polβ as identified using RT-PCR. Results and Conclusion: Mutant DNA polβ mRNA was expressed in the trans- fected CHO cells. A cell line stably expressing mutant po113 is established.
